title: Ultraviolet four-wave mixing in the LP(02) fiber mode.
abstract: We report UV four-wave mixing in the LP(02) mode of a photonic crystal fiber when pumped by a frequency-doubled 532 nm microchip laser in the normal dispersion regime. A pure LP(02) mode was generated for the pump light by a broadband all-fiber mode converter. Ultraviolet signal wavelengths as short as 342 nm were generated.
